High for this changeable weather pattern to continue during first half of the week then for high pressure to bring more settled conditions later in the week.
Gale force winds (gusts over 50mph) make walking difficult and strenuous with a potential to be blown over by gusts. There is often a marked increase in winds through cols or on exposed ridges and summits. Distances can take longer to cover and compass bearings become harder to follow accurately.
Wind significantly lowers the ‘feels-like’ temperature relative to the actual temperature, with even moderate winds significantly adding to the chilling effect. Strong winds can result in a severe and debilitating wind chill many degrees below the actual temperature. This effect will be enhanced in rain or wet snow. Without protection, prolonged exposure could result in frost nip or frostbite on exposed parts of the body and/or hypothermia.
Poor visibility presents challenging route finding conditions. Visibility could be significantly less than 50 metres in all directions with few or no visual references, especially on featureless moors or plateaux. Distances become hard to judge and cliff or cornice edges can be difficult to recognise. These conditions require good navigational skills. There is a risk of white-out conditions when mist or fog is combined with extensive snow cover.
Harmful UV levels from sunlight increase with altitude giving a greater risk of sunburn and eye damage, even on some overcast days. On breezy days, the cooling effect of wind on exposed skin may disguise any feeling of sunburn until it is too late. If there is snow cover, glare increases the effect of UV rays especially on the eyes. It is advisable to wear sun block, protective clothing such as a long-sleeved top and hat and have good quality eye protection.
Mainly dry, bright morning. Patchy rain during afternoon. Windy.

80% decreasing to 30% in the afternoon, improving again during the early evening. Occasional cloud cover in the morning around 800m will become more extensive during the afternoon at around 600 to 700m, lifting and breaking again during the evening. .
Generally very good but patches of moderate or poor visibility during afternoon.
Note the combination of gales on the tops and temperatures only a few degrees above freezing will result in a significant chill effect. Also gales over higher ridges and summits will make walking conditions difficult.
Dry and bright for much of the day with sunny spells. Just a few showers at first in west soon dying out. It will become cloudy during the afternoon with more persistent rain spreading in during the late afternoon and evening.
Westerly winds with average speeds of 30mph gusts 50 at first decreasing 15mph during afternoon and evening.
80% reducing 30% during late afternoon and evening. Patchy cloud cover around 800m becoming extensive and lowering 600 to 700m later in the day..
